On my way back from the South Downs twisties I decided to go off roading. Big mistake. About 1/4 mile into some woods and off I toppled. Strangely the bike didn't seem that heavy to lift and it kept going. But how on earth do you go off roading with a behemoth like the 1150 GS. Okay the tyres aren't brilliant and the ground was a bit slippy but nothing you wouldn't normally expect. Would it make a big differenece if I changed the Tourances for TKC 80s?
some folks manage some real difficult terrain on them 



and the wrong profile for your bike by a long way I think.
